Description
Version:
Version suitable for NC with straight shank ⌀ for the standardised toolholder, specially in hydraulic chucks or high-accuracy chucks.
This ensures very high concentricity and process reliability.
It is no longer necessary to procure special arbors.
With internal coolant feed for HPC use to reduce production costs.
With short, straight flutes.
Tolerance specifications:
Configurable:Reamers finish ground to match your specification.
H7: Version to DIN1420 for H7 bore tolerance.
